Application filed September 1'7, 1906. Serial No. 334,856.

To a/ZZ whom, it ncty con/067%:

Be it known that I,GEORGE MOORE, a citizen of the United States, and a resident of Granite Falls, in the county of Snohomish and State of lvashington, have invented a new and Improved Logging Device, of which the following is a full, clear, and exact description.

The invention relates to logging devices, such as shown and described in the Letters Patent of the United States No. 751,322, granted to me February 2, 1904.

The object of the present invention is to provide a new` and improved logging device arranged to permit convenient running of the logs down steep grades under perfect control of the operator and without danger of injuring the logs or wasting time.

The invention consists of novel features and parts and combinations of the same, which will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure I is a side elevation of the improvement. Fig. 2is an enlarged front elevation of the brake mechanism for the holdbackcable, and Fig. 3 is a plan view of the holdback-cable drum and connected parts.

A log or plurality of coupled logs A A, to be moved down a chute or skid-road B, are connected at the forward end with a pull-cable O and at the rear end with a holdback-cable D, and the said pull-cable O winds and unwinds on a drum E of a donkey-engine or other motor F, located at the delivery end B of the chute or skid-road B. The holdbackcable D winds and unwinds on the gypsydrum G of a4 brake mechanism. I-I, wound on a suitable framework, shown located at the starting-point B2 of the chute or skid-road B, as plainly indicated in Fig. l. The shaft G of the drum G is journaled in suitable bearings on the framework I, and on the said shaft G is secured or formedan auxiliary drum J, on which winds and unwinds an operatingcable K, extending down the hill at one side of the chute or skid-road B to wind and unwind on a drum L, controlled by the donkeyengine F.

The brake mechanism I-I for the gypsydrum G is preferably of the saine construction as the one shown and described in the Letters Patent of the United States above with the logs A, as previously described, and

then a signal is given in any suitable manner to the engineer in charge of the donkey-engine F to start the drum E for winding up the pull-cable O and for allowing the'cable D to unwind from the drum G. When this takes-7 5 place, the pull-cable O pulls the logs onto the skid-road B from the starting-point B2, and when the logs pass down the steep portion of the chute or skid-road B then the operator in charge of the brake mechanism H manipulates the latter to brake the drum G, so that the holdback cable D prevents the logs from traveling too fast down the steep portion of the skid-road-that is the holdbackcable holds the logs back for the latter to travel at a desired rate of speed when traveling down the steepest portion of the skidroad. Vhen the logs again come to a level portion or even an upgrade in the skid-road, then the operator in charge of the brake mechanism H releases the grip on the brakewheels H to permit the pull-cable O to easily pull the logs along the level or upgrade por-' tion until the logs again pass to asteep portion in the road, at which time the brake mechanism again is set in action and the above operation is repeated until the logs have safely reached the lower end B of the skid-road adjacent to the donkey-engine F, located near a watercourse. During the time the pull-cable O. winds up on the drum E and the holdback-cable D unwinds from the drum G the operating-cable K winds up on the auxiliary drum land unwinds from the drum L. N ow when the pull-cable C and the holdb ack-cable D have been disconnected from the logs A at the delivery end B .of the skid-road B then the adjacent ends of the said cables O and D are coupled together, after which the drum L is rotated from the donkey-engine F to wind up the operatingcable K. Now when this takes place the op- IOO IIO

lwith it the pull-cable C, coupled to the holdback-cable D. Thus by the arrangement described the holdback-cable D, as well as the pull-cable C, are returned with their ends to the starting-point B2 to permit of connecting the pull-cable O and the holdback-cable D to another log or a plurality of coupled logs, the same as previously described..

From the foregoing it will be seen that by the arrangement described the winding up of the holdback-cable D is controlled from the landing or delivery end B of the skid-road B, and consequently very little time is lost in the logging operations to permit oi' hauling a large number of logs in a given time.

The device can also be readily used in railroad-logging for hauling a loaded'train up a steep hill and letting it down to the landing. in this case the device is located on top ofthe Having thus described my invention, IV

claiml as new and desire to secure by Letters Patent- 1. A logging device, comprising drums at the starting-point and delivery-point of the logs, respectively, a pull-cable winding on the drum at the delivery-point, a holdback-cable winding on the drum at the starting-point, and means controlled from the delivery-point for operating both drums.

2. A logging device provided with a holdback-cable for connection with a log to hold the latter back, a drum for the holdbackcable to wind on and to unwind., a brake mechanism for the said drum, the latter and the said brake mechanism being located at the starting-point oi the log, and means located at the delivery end of the log and connected with the said drum for actuating the same to rewind the holdback-cable.

3. A logging device provided with a pullcable for connection with a log for pulling the latter, a holdbacli-cable arranged for connection with the log and for holding the log back, means for winding the said pull-cable at the delivery .end of the log, a brake mechanism, a drum for the said holdback-cable and adapted. to be controlled by the said brake mechanism when unwinding the holdback-cable, and

an actuating device for the said drum to ro tate the drum for winding up the holdbackcable to return the pull-cable coupled to the lioldback-cable.

4. A logging device provided with a pullcable for pulling a log, a holdback-cable for holding back the log, a drum for the holdback-cable to wind on and to unwind and located at the starting-point of the log, means at the delivery end of the log forwindingup the pullcable, and an actuating device for the said holdback-cable drum to rotate the latter for rewinding the holdback-cable, the said actuating device being actuated at the delivery end of the log. l

5. A logging device provided with a pullicable for pulling a log, a holdbaclr-cable ior holding back the log, a drum for the hold'- back-cable to wind on and to unwind and located at the starting-point of the log, an auxiliary drum rotating with the saidy holdback-cable drum, an operating-cable winding and unwinding on the said auxiliary drum and in a direction opposite to that of the holdback-cable on its drum, and means located at the delivery-point of the log for winding up the said operating-cable.

6. A logging device provided with a pullcable for pulling a log, a holdback-cable for holding back the log, a drum for the holdbacl-cable to wind on and tounwind and located at the starting-point of the log, an auxiliary drum rotating with the said holdbaclvcable drum, an operatingecable winding and unwinding on the said auxiliary drum and in a direction opposite to that of the holdback-cable on its drum, and a donkey-engine located at the delivery-point of the log, and having drums for the said pullcable and the said operating-cable.

In testimony whereof .l have signed my name to this speciiication in the presence of two subscribing witnesses.
